Mystery 396 casting date

[mr396]

Here is something you don't see everyday.The block casting number is G 10 8, July 10,1968. The engine pad is stamped T0709 July 9,1968. any idea how this could happen?

If all is genuine, I'd suspect the boys just didn't change the gang stamp for block stamping and the earlier stamp date ends up on the later casting block. . How much time usually goes by from casting to assembly? . What I'm wondering now is, isn't this Vin shown 18N468959 in the range of a June build car? ~ Pete

This car was put in storage in 1977 with 50,000 miles on it.I bought it 1n 1984 with the 1977 lic plates still on it. It now has 68,000 original miles and I have all the service records.and pop.I too would like to know how long after casting do they stamp it.

can you tell from the picture if the broach marks look ok? Does the vin #468959 fit with a 07C build?

This is not unusual per Jeff Dotterer of Dated Components. The Deuce engines generally have an 3-5 day span betw/ the casting date and the assy date, far too close I thought, but apparently not (?)

I would say it is rather unusual to have an engine pad stamped prior to the engine being cast. I have never seen this with a factory stamping prior. It would have to be a factory mistake,IMO.

I checked the CRG web site and found the 1967-1969 end-of-month vin report.It says Nor numbers are... end of may 68 vin# 465482 and June 68 482588..... That would make my 468959 a June 68 build.I think the CRG should look in to this and correct it. http://www.camaros.org/geninfo.shtml

There's nothing to correct. Several months are off, that being one of them. Please read all the caveats that are posted before that data. That is from GM records. Maybe GM will correct it, but I'm not sure who to ask.
